IntesisBox® Modbus Server – Mitsubishi Heavy Industries AC
User’s Manual r1.0 eng
1. Description
1.1 Introduction
IntesisBox® Modbus Server – Mitsubishi Heavy Industries AC is a communication gateway
for Mitsubishi Heavy Industries air conditioning (AC) systems to Modbus slave (RTU and
TCP).
This gateway allows integrating a Mitsubishi Heavy Industries AC system inside a
supervision/control/automation system through PLC, SCADA and, in general, through any
device or system with Modbus mastering (TCP or RTU) interface.
The aim of this integration is to make accessible several Mitsubishi Heavy Industries air
conditioning indoor units communicating with the Superlink protocol as if they were part of
a Modbus system. Therefore, the IntesisBox® Modbus Server acts as a Modbus slave in the
Modbus interface, allowing the Modbus master read and write in the Modbus registers.
Moreover, IntesisBox® includes all hardware required to manage/control Mitsubishi Heavy
Industries indoor units without extra components needed.
1.2 Integration signals
Following is the list of parameters that can be monitored/controlled on the indoor units
using IntesisBox®:

For each indoor unit in the system:
o Communication Status (read-only)
o On/Off (R/W)
o Operation Mode (R/W)
o SetPoint Temperature (R/W)
o Fan Speed (R/W)
o Remote Controller Lock/Unlock (R/W)
o Louver Control (R/W)
o Room Temperature (read-only)
o Filter Sign Status (read-only)
o Error Code (read-only)
o Compressor Status (read-only)
o Filter Sign Reset (write-only)
o Remote Controller Error Reset (write-only)
o Thermo On/Off Status (read-only)
Apart from these, the IntesisBox® also implements some extra signals (functions):

1
For all indoor units1 in the system:
o HW Communication Status (read-only)
o On/Off (write-only)
o Operation Mode (write-only)
o SetPoint Temperature (write-only)
o Fan Speed (write-only)
o Remote Controller Lock/Unlock (write-only)
These signals work as master signals controlling all connected units at the same time

1.3 Functionality
Each of the mentioned signals in section 1.2 is associated to a predefined and fixed Modbus
address. Therefore, all the system is seen as a single Modbus slave unit with a fixed Modbus
address map from the Modbus system point of view.

Figure 1.1 Integration of Mitsubishi Heavy Industries AC into Modbus system using IntesisBox®
Two Modbus mode connection types can be active in IntesisBox®: Modbus RTU or Modbus
TCP, or both simultaneously.
IntesisBox® continuously polls all signals provided by each indoor unit and maintains the
updated values to be served in Modbus.
In the continuous polling of each indoor unit, if no response of a certain device is detected,
the corresponding virtual signal inside the gateway will be activated indicating
communication error between the gateway and that precise device (see 0).
When a write order is done from Modbus in a gateway's write-enabled Modbus address, the
corresponding order is sent to the associated Mitsubishi Heavy Industries signal (Superlink).
Each Mitsubishi Heavy Industries Indoor Unit has a unique address (0 to 127). These
addresses need to be configured inside IntesisBox® using the LinkBoxMB tool (see 4.2.2).
IntesisBox® is capable of managing up to two simultaneous Modbus master connections.
IntesisBox® includes all hardware needed to connect directly with the Mitsubishi Heavy
Industries indoor units connecting with Superlink network.
